People occasionally ask us for project/workspace (.DSP/.DSW) files to
compile PuTTY with Visual C++, or offer to contribute them.

All of our Makefiles are derived from a single upstream source
(Recipe) by a script (mkfiles.pl), so that
we don't have to maintain N slightly different Makefiles. Therefore,
any contribution would have to take the form of an update to
mkfiles.pl and/or Recipe. We won't be able
to make use of a .DSP/.DSW file per se, because that brings with it
precisely the maintenance burden we're trying to avoid.

Also, we already supply a Visual C Makefile
(Makefile.vc), for use with nmake. We're
unlikely to add .DSP/.DSW support ourselves because we don't have much
use for it.

Update:mkfiles.pl now generates these project
files. Many thanks to Joe Yates.
